What Is Glycereth-6 Tricocoate?
Glycereth-6 Tricocoate is a plant-derived ingredient made by combining coconut fatty acids with glycerin that has been reacted with six units of ethylene oxide. The result is a mild triester that behaves a lot like the skin’s own lipids, helping products feel rich yet non-greasy. It first appeared in cosmetic labs in the late 1980s when formulators began replacing heavier mineral oils with lighter plant alternatives. Production starts with coconut oil that is split into fatty acids, which are then esterified with glycereth-6, followed by careful purification to remove any unreacted material. Thanks to this method the final ingredient is clear, low odor and easy to blend. You will most often spot it in daily moisturizers, soothing masks, lightweight lotions, creamy makeup bases, sunscreens, leave-on hair conditioners and after-sun treatments.
Glycereth-6 Tricocoate’s Cosmetic Benefits/Uses
In formulas Glycereth-6 Tricocoate serves one main role:
Emollient: It softens and smooths the skin surface, adds a velvety slip to creams and lotions and helps lock in moisture without leaving a heavy film. This improves spreadability, boosts the overall sensory feel of a product and can make other active ingredients apply more evenly.
Who Can Use Glycereth-6 Tricocoate
This silky emollient suits nearly every skin type. Dry or mature skin enjoys its moisture-sealing feel while oily or combination skin appreciates that it absorbs quickly and does not leave a greasy residue. Sensitive skin generally tolerates it well because it is low in fragrance and free of common irritants. There are no known reasons for those with rosacea, eczema or acne-prone skin to avoid it, although each person’s experience can vary.
The ingredient is plant-derived from coconut oil so it is suitable for vegetarians and vegans.
No published data suggests any risk for women who are pregnant or breastfeeding when the ingredient is used topically at the low concentrations found in cosmetics. This is not medical advice and anyone who is pregnant or nursing should run any skincare product past a qualified doctor just to be safe.
Glycereth-6 Tricocoate is not known to cause photosensitivity, meaning it will not make skin more likely to burn in the sun. It plays well with most other cosmetic ingredients and does not interfere with sunscreen filters or actives like retinol or vitamin C.
Potential Side Effects/Adverse Reactions
Side effects and reactions to the topical application of Glycereth-6 Tricocoate can vary from person to person. The points below list potential issues yet they are uncommon for most users when the ingredient has been properly formulated.
- Mild redness or itching in those with very reactive skin
- Transient stinging if applied to broken or freshly exfoliated skin
- Contact dermatitis in rare cases of true allergy to coconut derivatives or polyethylene glycol compounds
- Clogged pores if used in an overly rich formula on extremely oily skin
If any negative reaction occurs stop using the product and seek advice from a healthcare professional.
Comedogenic Rating
Rating: 1 / 5 (very low)
Glycereth-6 Tricocoate is a light ester that spreads easily and rinses off with water thanks to its short polyethylene glycol chain. This reduces the chance of it building up inside pores. While coconut fatty acids on their own can be heavier, the chemical bonding to glycereth-6 makes the molecule more water compatible and less likely to trap dead cells or sebum. In most leave-on products it sits at low levels, further lowering risk.
Suitable for acne-prone or breakout-prone skin.
As with any ingredient, the overall formula and how much of it is used influence real-world performance. Very rich balms that combine this ester with high levels of waxes or butters could still feel pore-clogging for some users.
Summary
Glycereth-6 Tricocoate is a plant sourced emollient that softens skin, boosts slip and helps lock in light moisture without heaviness. It accomplishes this by mimicking skin lipids while its small PEG segment keeps it from feeling greasy or occlusive.
It is not a headline grabbing active yet formulators like it for the subtle silky feel it brings to everyday lotions, sunscreens and makeup bases so you will see it popping up in many mid-range and mass market products.
Current safety data shows it to be low risk for irritation, sensitization and pore clogging when used at cosmetic levels. Still, skin can be unpredictable so patch testing any new product remains a smart habit.
